• • No sponsor meeting this week. Sponsors both traveling.

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

• • put your own properties of plywood for FEA of the container made out of plywood (April 25, in person)

    • make it out of plate elements to perform FEA

    • hexahedral creates too many nodes

    • remove hinges and support brackets for FEA

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • Estelle (May 4, via email)

    • -What did the sponsor say about extra equipment (ie: a crane) being necessary for the implementation of your design? Does that go against any unspoken objectives of the project in any way?

  •  Cool FEA analysis for various cases and visuals of modified design.

  • Clear visuals.

  • Michael (May 4, via email)

    • Confused on idea for quick release pins. Wasn’t a crane going to be involved earlier?

    • That makes me think quick release is poor choice. I may have missed something said during the presentation

    • Slides were professional and did better with FEA diagrams. Glad I could see the numbers this time!

  • Maris (May 4, via email)

  •  Models are super helpful in understanding how it works

  •  I like the new design idea

  • Erik (May 4, via email)

  • Great CAD/FEA  images

  • I like the new design concept
